Chrysanthemum plant named ‘Dash’

ABSTRACT

A distinct cultivar of Chrysanthemum plant named ‘Dash’, characterized by its small anemone-type inflorescences that are about 3.7 cm in diameter; attractive golden yellow-colored ray and disc florets; response time about 68 days; freely flowering habit; dark green foliage; dark purple-colored stems; and excellent postproduction longevity with inflorescences maintaining good substance and color for about three weeks in an interior environment.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Dash’.

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new cut Chrysanthemum cultivars having inflorescences with desirable colors and good form and substance.

The new Chrysanthemum originated from a cross made by the Inventor in September, 1997, in Salinas, Calif., of a proprietary Chrysanthemum seedling selection identified as code number K548, not patented, as the female, or seed, parent with a proprietary Chrysanthemum seedling selection identified as H049, not patented, as the male, or pollen, parent.

The cultivar Dash was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Alva, Fla., in November, 1998. The selection of this plant was based on its desirable inflorescence color and good form and substance.

Asexual reproduction of the new Chrysanthemum by terminal cuttings taken in a controlled environment in Alva, Fla. since February, 1999, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Dash have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dash’. These characteristics in combination distinguish ‘Dash’ as a new and distinct cultivar:

1. Upright cut Chrysanthemum that is usually grown as a natural spray.

2. Freely flowering habit, about 8 inflorescences per flowering stem.

3. Small anemone-type inflorescences that are about 3.7 cm in diameter.

4. Attractive golden yellow-colored ray and disc florets.

5. Response time about 68 days.

6. Dark green foliage.

7. Dark purple-colored stems.

8. Excellent postproduction longevity with inflorescences maintaining good substance and color for about three weeks in an interior environment.

Plants of the female parent, the seedling selection identified as code number K548, and plants of the new Chrysanthemum differ in inflorescence form and color as plants of the female parent have daisy-type inflorescences with dark pink-colored ray florets.

Plants of the male parent, the seedling selection identified as code number H049, and plants of the new Chrysanthemum differ primarily in inflorescence color as ray florets of the male parent are white in color.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Fargo, disclosed in U.S. Plant Pat. No. 9,108. In side-by-side comparisons conducted by the Inventor in Madrid, Cundinamarca, Colombia, South America, plants of the new Chrysanthemum are more vigorous than plants of the cultivar Fargo. In addition, plants of the cultivar Fargo have daisy-type inflorescences whereas plants of the new Chrysanthemum have anemone-type inflorescences.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in Madrid, Cundinamarca, Colombia, South America, under conditions which approximate commercial practice in a single-layer polyethylene-covered greenhouse. Two-week old rooted cuttings were planted on Nov. 30, 2000 and received 14 long day/short nights followed by short day/long nights until flowering. Plants were grown as single-stem natural spray cut Chrysanthemums. During the production time, the following environmental conditions were measured: day temperatures, 19 to 24° C.; night temperatures, 4 to 12° C.; and light levels, 3,000 to 5,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems and were taken about 9 to 10 weeks after the start of short days.
